Again my DSL modem locked up last night when I posted...
Here I go again:
I have installed a few Zex and NOS systems and they are very good as a stand alone.
I personaly would have gone with a wet setup because it will take the fuel adding issue out of the PCM and factory injectors.
Don't forget to buy the "Blow-Down" tube. this is a safety item.
I used an RPM Window switch in two cars before throwing it down a mountain.[}

The reason is that you have to be very picky with the RPM selector.
When it closes the window and stops the Nitrous, the PCM will take a few secconds to notice this, the car will backfire because it is extremly rich, then goes to a lean condition( the PCM correcting), when you shift and the switch opens the flow of Nitrous, then it can be very lean for a seccond. Catastrofic!
It will work but you need to open the window to a setting over the MAX RPM, making it a little useless.
I used the window swich successfully in a 1974 Dart with a 360 engine and an NOS cheater system using a 175HP setting. the reason for the window switch was to delay the N2O at the line. The car had horrible traction problems at the 60 foot area. Once we fixed the traction problem with subframe connectors and taller tires, the window switch is now a passenger in the car (no more windows). it is now at the 11.8 sec world on the bottle. next level 225 N2O shot[}
